To all whom t may concern.'

Be it known that I, LOUIS GRnENwALma citizen of Russia, residing at Woodlawn, 1n the county of Beaver and State of Pennsylvania, have invented certain new and useful VImprovements in Umbrellas, of which the following is a specification.l

VThis invention relates to improvements in umbrellas and it Vis the principal object `of i I stick,

the invention to provide a foldable umbrella capable of being folded into compact form when not in use, whereby the same can be conveniently carried or packed, but which, when opened will aiiord an exceedingly eiiicient shelter and also `will be prevented from vunduly collasping.

Another and equally important object of the invention is to provide an umbrella having novel stays or ribs, which willserve to maintain the same infullV open position and also causethe fabric covering thereof to be arranged taut over the same. y

Yet another object of the invention is to provide an umbrella having a collapsible stick so constructed as to permit the telescoping of the various sections thereof when it is not desired to use the same.

The invention consists, furthermore, in the novel arrangements and combinations of the parts of the umbrella, as well as in the details of the construction of the same, all of which will be more fully described in the following specification and then finally embodied in the clauses of the claim,lwhich are appended to the specification and which form an essential part of the same.

In the drawings:

Figure l is a vertical section through the improved umbrella,

Fig. 2 is afragmentary section through a portion of the stick'thereof,

Fig.A Sis a fragmentary side elevation of the stick,

Fig. 4L tionthrough a slidable sleeve, Y

Fig. 5 is a horizontal section through the portion of the stick and the Fig. 6 isa detail in perspective of one l.of the elements, i

Fig. 7 is a detail of the connection between portions of the folding ribs, and

Having more particular reference to the drawings, in connection with which like is a fragmentary longitudinal sec` vthe numeral 2 being formed to constitute an effectual handle for, the same. Openings 3 and notches or seats 4L are formed in the adjacent portions of the sections l and are adapted to be alined at times, whereby the off-set end of substantially V-shaped latch elements 5 may be passed therethrough, said elements,'obviously, being arranged in the tubular sections and so positioned as to be sequentially engaged by the adjacent inner sections upon the telescoping of the same, in a manner hereinafter more fully described. To prevent relative rotation of the sections, longitudinally disposed key ways 6 are formed in the sections and receive keys in form of screws 7 therein, said screws being carried by annular collars 8 arranged in and `secured to said sections 1 in a suitable manshoulder thereof engaged with the adjacent end of the next section l. Obviously, by depressing the spring latch 9, the same may be caused to move within the adjacent section l by moving the section 2. In this con* fnection, it is to be noted that the section 2 is also formed of tubular material, similar to the sections 1.

FiXedly engaged with the upper end of the outermost section 1 is a ferrule 10, while a sleeve 11 is slidably arranged on the intermediate portion thereof and is provided with apertured bearing lugs. To maintain the sleeve 1l in its uppermost position in order that the umbrella can be held open, a spring pressed latch pin 12 is slidably arp A. ranged therein and is adapted to be engaged Fig. 8 is a similar-view of a connection be tween other portions of the folding ribs.

in an opening 13V formed in said outer section l.

nected links 14, certain of which are of less length than the others in order thatV the usual curve of the umbrella Vwhen in openposition will be permitted. Stop pins 14 'are carried on enlarged ends of some of the links 14 and serve for a purpose hereinafter described. The arrangement of the pivotally connected cross links 14 is such as to constitute the usual lazy tong construction; the inner ends of the ribs being pivotally connected at points about the errule 10 as is arranged in the upper end of theouter section 1 and isi-idapted to receive a set screw 21 therein, said set screw having the head of the same bearing on a metal washer 22 which in turn is arranged upon fabric or `leather washers 23, these washers having engagement with the adjacent portions of the covering 19 and serving to securely bind the sane-.ein position. To render the ribs continuous in order that the covering 19 will be arranged taut thereover, a plurality of links 24 are provided and have their adjacent-ends pivotally connected; the outer links being pivotally connected to the adjacent portions of the fiexible rods 17 while the inner links are pivotally connected to portions of the 'errule 10 adjacent the connection 15 of certain of the links constitutingfthe ribs 14.

Recesses are formed in the ends of the outer links and receive the stop pins 14 therein when in open position to prevent undue movement of said links as clearly shown in Figs. 7 and S.

In using the improved umbrella, to open the saine the handle section 2 is engaged and pulled outwardly, thus causing the same and the sections 1 to be moved to their distended positions whereupon the spring latch 9 will engage the adjacent end of the section re@ ceiving said handle section2 and the off-set ends of the latching elements 5 will pass into the seats 4 formed in the adjacent portions of the sections 1 next thereto. In this way, it will be readily understood that the sections constituting the stick of the umbrella will be Vsecurely held in their distended or open positions. The sleeve 11 is now grasped and moved upwardly on the outer section 1 thus expanding the ribs 14 and causing `the Copies of this patent may bepobtainjedpfor five cents each, by addressing the #Commissioner of Patents, f

Flexible rods 17 are covering to be moved to its open position,

whereupon the latch pin 12 vis engaged in the opening `13, thus `preventingv further movement of the sleeve 11. To close the umbrella, it is only necessary to disengage the latch pin 12 from the opening and move the sleeve -11 ydownwardly on its respectivesee tion l thus collapsing the ribs 14 and compactly folding the saine and the cover 19. At this time, the spring latch9 is depressed inorder thatthe handle section 2 may be telescoped in the adjacent section 1, wher -i uponpach of said sections are. telescoped in seq uenti alv l order,l thus causing 4the V-shaped latch elen'ients 5 to besequentially,engaged trom their respective `seatsj4 in the Vvarious 1.

said links being` of greaterlengths than the others, and a series of pivotally connected links engaged with the outer ends fof said iirst links, stick and rods and 'adapted to span the space between said stick androds.

In testimony whereof, I aiiix my sigriaf ture hereto.
